^^ This. I'm close to 400 and when properly warmed up have grip in all gears except 1st on NT05s. Unless you have the money to spend on NT01s. R-compounds are always better

Great numbers man, that curve looks awesome. They're doing some great tuning. On a DD you're at 430 whp with 93 octane then? Thats awesome!

Here is the video, this is still on the 93 at 24 psi, I rolled on throttle going wot at around 65-70 so it wouldnt spin as bad, and got the boost dialed in a bit, about 20 psi in third and 24 in fourth. hope you enjoy. I used the gopro so thats why the video looks like it does.

external dump?

night and day difference from your s252 setup @ 25psi

I'm afraid this efr 6758 is going to be too small for me. LOL.

Can tell the gearing is different too. Looks like it's better for racing, 4th seems to get you at a good point by the end.

Was your s252 kit a T4 setup? Couldn't zzp put on an efr 7064 instead of the 252? Maybe it's not that simple

Dont mind the wideband readings, the wideband was acting goofy all day, the logs show a nice perfectly smooth flat line. Thanks again to ZZP and Matt and Ryan especially.

thats no 4 cylinder!!!! thats a rocketship!

I only had the s252. I went with the 5857 after building the motor.
